Properties

CssClass

Gets or sets the custom CSS class of Gantt EventMarker to customize background and label.

Declaration
[Parameter]
public string CssClass { get; set; }
Property Value
Type Description
string

A string value that represents the custom CSS class of the Gantt event marker.
Remarks

This property is used to define a custom CSS class for the Gantt event marker. The custom CSS class can be used to customize the background and label of the event marker. If the property is not set, the default CSS class will be used.

Day

Gets or sets the date of Gantt EventMarker.

Declaration
[Parameter]
public DateTime Day { get; set; }
Property Value
Type Description
DateTime

A DateTime value that represents the date of the Gantt event marker.
Remarks

This property is used to define the date of the Gantt event marker. The event marker will be displayed on the specified date.

Label

Gets or sets label of Gantt EventMarker.

Declaration
[Parameter]
public string Label { get; set; }
Property Value
Type Description
string

A string value that represents the label of the Gantt event marker.
Remarks

This property is used to define the label of the Gantt event marker. The label will be displayed on the event marker. If the property is not set, no label will be displayed.

Top

Gets or sets the vertical position, in pixels, of the Gantt Event Marker label.

Declaration
[Parameter]
public string Top { get; set; }
Property Value
Type Description
string

A string value expressed as a CSS length in pixels (for example, "50px" or "100px"). Only positive pixel values are accepted. Any value that is not a positive pixel string (for example, negative values, "%", "rem", "em", "vh", unitless numbers, or Empty) falls back to the default vertical position of "50px".
Remarks

Use Top to control the vertical position of Event Marker labels when multiple Event Markers are rendered on the same Day, helping to prevent label overlap. If an invalid or negative value is specified, the Event Marker is rendered using the default vertical position of "50px".

When multiple Event Markers share the same Day and the Top property is not specified for each marker, all labels are rendered using the default position of "50px". No automatic stacking, collision avoidance, or position calculation is applied, and Event Markers rendered at the same position may overlap.

The Top property affects only the vertical placement of the Event Marker label. The Event Marker timeline indicator line continues to use its existing rendering logic and is not repositioned by Top. Labels rendered outside the visible timeline container are clipped by the container boundaries.
